    <p>I'm stumped why I cannot make the temp table in the bash script.</p> <p>This works on the command prompt.</p> <pre><code>mysql&gt; CREATE TEMPORARY TABLE snorby.delete_me ( SELECT cid AS del_cid FROM snorby.event WHERE timestamp &lt; DATE_SUB(NOW(), INTERVAL 21 DAY) ); Query OK, 72 rows affected (0.08 sec) Records: 72 Duplicates: 0 Warnings: 0 mysql&gt; select * from snorby.delete_me limit 2; +---------+ | del_cid | +---------+ | 4 | | 5 | +---------+ 2 rows in set (0.00 sec) mysql&gt; DROP TABLE snorby.delete_me; Query OK, 0 rows affected (0.08 sec) mysql&gt; </code></pre> <p>But when I do that from the command line, intending to use it in the bash script, it does not make a table. Note: this root user has no password.</p> <pre><code>~$ sudo mysql -uroot -e "CREATE TEMPORARY TABLE snorby.delete_me (SELECT cid AS del_cid FROM snorby.event WHERE timestamp &lt; DATE_SUB(NOW(), INTERVAL 21 DAY) );" ~$ sudo mysql -uroot -e "SELECT * FROM snorby.delete_me LIMIT 2;" ERROR 1146 (42S02) at line 1: Table 'snorby.delete_me' doesn't exist </code></pre> <p>Lastly, if I put those commands in a .sql file and run them it also works fine. Example:</p> <pre><code>~$ mysql -uroot -e "SET @daystokeep=21; source snorby_del_old_by_days.sql;" </code></pre> <p>Thanks to barmar, I understand now. To run the whole thing from the command, it must be all one command, if using the temp table. Ex:</p> <pre><code>~$ sudo mysql -uroot -e "CREATE TEMPORARY TABLE snorby.delete_me (SELECT cid AS del_cid FROM snorby.event WHERE timestamp &lt; DATE_SUB(NOW(), INTERVAL 21 DAY) ); SELECT * FROM snorby.delete_me LIMIT 2; DROP TABLE snorby.delete_me;" </code></pre> <p>Or use a regular table.</p> <p>I thanks for the help.</p>

    1. COIf you want the table to persist between MySQL invocations, why are you making it temporary? What do you think temporary means?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
